Be it known that l, (Jr-menus E. Noun woon, a citizen of the United States, and residing at Bethlehem, Northampton County, State of Pennsylvania, have invented certain new and useful Improvements in Apparatus for Sealing @penings, oi which the following is a specification.

The present invention relates to apparatus for sealing the cracks or oints around openpresent invention to provide a machine vention a gun like the common cement gun s ings such as coke oven door.

l-leretotore the cracks or joints around coke oven doors and the like have been by hand. llt is the principal aim or the for accomplishing this result. To this end the invention consists in the provision of means for delivering sealing material around the edges of the door. in one form of the i provided and this supplies the sealing material to a nozzle, which is adjusted to cause the jet of sealing material to travel around the edges of the door.

The objects and features of novelty will be apparent from the description taken in connection with the drawings, in which- Fig. 1 is a side elevation of one form of apparatus constructed in accordance with the present invention and mounted on a car or truck adapted to travel along in front of a ha 'tery of ovens, the housing being re moved; I

Fig. 2 is an end view or the apparatus;

3 is a. partial plan view of the apparatus;

Fig. l is a sectional elevation taken through the upright or guide substantially on the line l l of Figure 5; and

Fig. 5 is a sectional. plan view talren substantially on the line 5--5 of Figure 1-.

Referring to the drawings and more par-- ticularly to Figure 1, the reference numeral 10 indicates the outline oi? one or the oven openings or doors, the same being indicated by dotted lines. It is to be understood there are a series of these openings. in is the main object or the present invention to provide means for sealing cracks around the edges of the oven. doorsin the torm or" Serial No. 415,205.

the invention illustrated, the apparatus is mounted on a car or truck 11 having wheels 12 running on a track 13 disposed along in front or the oven doors. The car is equipped with a motor 14-, under the control of an operator on a seat 15 near one end of the car, a suitable motor controller 16 adjacent the seat being provided for starting and stopping the motor. @LE course suitable means (not shown) is provided for conveying electric current to the motor.

the form of the invention shown the sealing material is discharged around the edges or": the door from a nozzle 17. This nozzle is supplied with sealing material under pressure in any suitable manner; Thus an apparatus such as used in connection with cement guns may be employed. This apparatus may comprise an air compressor 18 operated by a suitable motor (not shown) supply ng compressed air to a reservoir 19. it conduit 20 connects the compressed air reservoir and the cement gun 21 having a hopper 22 at its upper end through which the gun is supplied with suitable material such as clay. A water tank 23 is provided the water therein is put under pressure by placing the tank in communication with the compressed air reservoir through the conduit 2%. Thus water is forced to the gun through the conduit 25. From the gun a suitable conduit 26, such as a hose, leads to the nozzle 17.

According to the present invention the nozzle is mounted so that it may be adjusted to cause the jet of sealing material issuing therefrom to travel around the edges of the door. As shown the nozzle is mounted "for movement both vertically and horizontally so that is adjusted to cause the jet to travel up one side of the door along the top down the other and then along the bottom. Although the nozzle is shown as mounted for movement both vertically and tical sL-anrhml thereon, oi". a carri vertically on said standard, a nozzle on said carriage, connections between said tank, compressor, gun and nozzle, a screw'to traverse said arriage on said stancard, an air motor for driving said screw, connections hetveensaid compressor and motor, means to cishion said carriage the ends of its travel, and means to move said nozzle horizontally on said carriage.

8. Apparatus for luting coke oven doors and the like. comprising the combination with a truck having a cement gun plant including: a nozzle, means to feed said nozzle vertically in either direction on said truck, and means to shift said nozzle horizontally.

9. Apparatus for lilting coke oven doors and the like, comprising a. standard, a carriage slidahle up and down thereon, power means for reciprocating said carriage, a ram horizontally slidahle on said carriage and having' racl: teeth thereon, a shaft carrying pinion in mesh with said rack, a parallel shaft provided With a hand operating lever, gears connecting said shafts, a nozzle carried by said. ram, and means to supply sealing' material under presssure to said nozzle.

10. Apparatus for luting coke oven doors and the like, comprisinga nozzle and means to supply material under pressure thereto, means to feed said nozzle vertically up and down the sides of a door, ant. manual means to feed it horizontally along the top and hottom of the door.

11. .Apparatus for sealinv; the cracks around an oven door, including in comhination, a nozzle, means to supply said nozzle With sealing material, and means to a said nozzle to cause the jet of sealing material issuing therefrom to travel around the edges of said door.

12. Apparatus for sealing the cracks around an oven door, including in coinhination, a nozzle, means to supply said nozzle With sealing material, means to raise and lower said nozzle to seal the side edges of the door, and means to adjust said nozzle to cause the jet of sealing material issuing: there from to travel horizontally to seal e top and bottom edges of the door.

13. E'rpparatus for sealino,- the craclrs around an oven door, including in combination, a nozzle, means to adjust the nozzle to cause the jet of sealing material. issuing; therefrom to travel vertically to seal toe side edges of the door, and means to move the nozzle horizontally to seal be top and bottom edges.

14:. Apparatus for luting colre oven doors and the like including in combinz'rtion, a car traveling in front of the oven door, a nozzle for discharging sealing material, a support for said nozzle carried by the car. means on the car to feed said support in either of two directions an angle to each other and a slidahle sealin the cracks in combihy said car to discharge a jet of sealing: material, and means to move the jet to cause it to travel around the outer edges of said door.

16. Apparatus for sealing the cracks around an oven door including in combination a car, and means carried by said car to discharge a jet of sealing material around the edges of the door.
